Be it known that I, Lonnwrcn Hoonn- BEEK, a citizen of the United States, residing at Newark, in the county of Essex and Stateof New Jersey, have invented certain new and useful lm rovements in Electrodeposition of Nonetallic Bodies; and I do hereby declare the following to be a full, clear, and exact description of the inventlon, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accom a-,

, nying drawings, and to characters of re erence marked thereon, which form a part of this specification.

The present invention relates, generally, to a novel means, and method of providing surfaces of non-metallic bodies with a coating or veneer of electrolytically deposited metal, with a .view of providing wood or 4 other non-metallic surfaces with a metalcoated or veneered surface which, with'the contraction or expansion of'the non-metallic body, or with the shrinkage of the body, where improperly seasoned wood is employed for the base, will not bulge or strip from said base.

The present invention therefore has for its principal object, to provide a novel means, in the-form of anchoring devices in fixed attachment to said non-metallic body, to which electrolyticall "deposited metal may attach itself and ad ere, for positively and perfectly maintaining the adhesion of the metal surface upon said non-metallic body or base,

against bulging, blistering, wrinkling or stripping therefrom.

Other objects of the present invention not at this time more particularly enumerated will be clearly understood from the followin detailed description of the invention.

ith' the various objects' of the present invention in view, the said invention consists in the novel application to a nonmetallic body or base, of suitable anchoring devices, upon or about which the metal, during the process of electrodeposition, so as to positively and permanently secure the metal coating or veneer against bulging or stripping from the surface of the said nonmetallic body or base.

Serial in). waste. ToaZl'who m z'tmay concern: metal coating or veneer secured thereto by means of one style of anchoring devices; and Fig. 2 is a plan or top view of the nonmetallic body or base with the anchoring devices shown in said figure, prior to the provision of the surface of the said nonmetallic body with the coating or veneer of electrolytically deposited metal.

Fig; 3 is a view similar tothat represented in said Fig. 1, but showing the non-- metallic body or base and the metal coating" or veneer united by means of anchoring devices of a modified construction; and Fig. 4, 1s a view similar to that represented in said, Fig. 2, said view illustrating the plan-arrangement of the non-metallic body or base and the anchoring devices representedin said Fig. 3.

Similar characters of reference are employed in the said above described views, to indicate corresponding parts.

Referring now to Figs. 1 and 2 of the drawings, the reference character 1'indi-' catesa suitable non-metallic body or base, which may be of wood in the form of a plank or other desirable shape, or which may be of any other suitable non-metallic material, fabric or the like. The reference character'2 indicates an application of varnish or suitable sizing for adherence to the wood or other non-metallic body or base 1, and'3 indicates a suitable layer of black lead graphite,'copper-bronze, silver leaf, or other like good conductor of electricity, secured to the surface of the said non-metallic body or base by means of the adhering material 2 herein-above mentioned.

Driven into the said body or base 1; through the twolayers 2 and 3, as shown in said Fig. 1, are suitably spaced anchorof the said devices in this case being provided with heads or enlargements 5 suffic ently exposed above 7 the upper surface of the said body or base 1, and the layers 2 and 3 thereon, to provide suitable anchoring or retaining means upon or about which portions of the electrolytically' deposited metal coating or veneer 8 will be formed and caused to adherev there to, so as to thoroughly attach itself to the said heads or enlargements in the deposited metal, as will be clearly evident.

The shanks of the said devices 4: are also preferably split, as at 6, so as to provide pointed elements, as 7, which when the said M anchoring devices are driven into position in the non-metallic body or base 1', will s'ufii- --ciently spread apart, as shown, thereby also relative to the latter. In Figs. 3 and- 4 of the illustrated the non-metallic body or base 1 mg slots or grooves .ranged suitable keys:

vide suitable anchoring means upon and,

about which portions of the metal coating or veneer are deposited, so as to thoroughly embed the projecting portions of the said keys in the deposited metal, whereby the latter attaches itself and adheres to said ke s. 4

Khe reference-characters 14: and" 15 indicate the usual circuit wires of an electrode ositing machine or apparatus of any In carr ing out the steps novel met 0d of providing the sur ace of a non-metallic body or base with a coating or veneer of electrolytically deposited metal, the surface or sur aces of the said body or base 1 are first painted with the coating of as 10, of metal, provid-- embod ing the varnish or sizing 2, and then the layer of electrical conducting material 3 for eposition is applied, the anchoring devices bein next secured-in their proper and desi'r locations. The electric circuit-wires 14; and 15 are then 'prope'rl attached and the electric current turne on so that the metal from the anodes of the depositing apparatus will be deposited upon the layer 3' and upon or about the exposed portions of the anchor-. ing devices, as will be clearly evident, and resulting in theproduct illustrated in Figs. 1 and 3 of the drawings. 1

Of course it will be evident, that the anchoring devices may be secured in their respective positions upon the non-metallic body or base 1, before the application of the layers '2 and 3 thereto, if desired; and, furthe'rmore,-other shapes of anchoring devices ma be employs .i, as will be clearly evident.
